RESUMEN

BACKGROUND: Alcohol and firearms are commonly involved in suicide in the United States. State alcohol and firearm policies may impact alcohol and firearm related suicide, yet little is known about these relationships. This study examines relationships between state alcohol and firearm policies and suicides involving alcohol, guns, or both, and explores interactive policy associations. METHODS: Alcohol policies were assessed with the Alcohol Policy Scale. Firearm policies were assessed using the Gun Law Scorecard from Giffords Law Center. Suicide data from the National Violent Death Reporting System in 2015 covered 22 states. State- and individual-level GEE Poisson and logistic regression models assessed relationships between policies and firearm- and/or alcohol-involved suicides with a 1-year lag. RESULTS: In 2015, there were 8996 suicide deaths with blood alcohol concentration test results in the 22 included states. Of those deaths, alcohol and/or firearms were involved in 5749 or 63.9%. Higher alcohol and gun law scores were associated with reduced incidence rates and odds of suicides involving either alcohol or firearms (adjusted incidence rate ratios [IRR] 0.72 (95% CI 0.63, 0.83) for alcohol policies, 0.86 (95% CI 0.82, 0.90) for firearm policies). Relationships were similar for suicides involving both alcohol and firearms, and there was an interactive effect, such that states with restrictive policies for both had the lowest rates of suicides involving alcohol or guns. CONCLUSIONS: More restrictive alcohol and firearm policies are associated with lower rates and odds of suicides involving alcohol or firearms, and alcohol and firearms, and may be a promising means by which to reduce suicide.

RESUMEN

BACKGROUND: Subclinical tuberculosis is an asymptomatic disease phase with important relevance to persons living with HIV. We describe the prevalence, clinical characteristics, and risk of mortality for HIV-infected adults with subclinical tuberculosis. METHODS: Untreated adults with HIV presenting for outpatient care in Durban, South Africa were screened for tuberculosis-related symptoms and had sputum tested by acid-fast bacilli smear and tuberculosis culture. Active tuberculosis and subclinical tuberculosis were defined as having any tuberculosis symptom or no tuberculosis symptoms with culture-positive sputum. We evaluated the association between tuberculosis disease category and 12-month survival using Cox regression, adjusting for age, sex, and CD4 count. RESULTS: Among 654 participants, 96 were diagnosed with active tuberculosis disease and 28 with subclinical disease. The median CD4 count was 68 (interquartile range 39-161) cells/mm3 in patients with active tuberculosis, 136 (72-312) cells/mm3 in patients with subclinical disease, and 249 (125-394) cells/mm3 in those without tuberculosis disease (P < 0.001). The proportion of smear positive cases did not differ significantly between the subclinical (29%) and active tuberculosis groups (14%, P 0.08). Risk of mortality was not increased in individuals with subclinical tuberculosis relative to no tuberculosis (adjusted hazard ratio 0.84, 95% confidence interval 0.26-2.73). CONCLUSIONS: Nearly one-quarter of tuberculosis cases among HIV-infected adults were subclinical, which was characterized by an intermediate degree of immunosuppression. Although there was no significant difference in survival, anti-tuberculous treatment of subclinical cases was common. TRIAL REGISTRATION: Prospectively registered on ClinicalTrials.gov , NCT01188941 (August 26, 2010).

RESUMEN

BACKGROUND/AIMS: Reproducible outcomes in clinical trials depend on adherence to study protocol. Short message service (also known as text message) reminders have been shown to improve clinical trial adherence in the United States and elsewhere. However, due to systematic differences in mobile data plans, languages, and technology, these systems are not easily translated to international settings. METHODS: To gauge technical capabilities for international projects, we developed SMSMessenger, an automated Android application that uses a US server to send medication reminders to participants in a clinical trial in St. Petersburg, Russia (Zinc for HIV disease among alcohol users-a randomized controlled trial in the Russia Alcohol Research Collaboration on HIV/AIDS cohort). The application is downloaded once onto an Android study phone. When it is time for the text message reminders to be sent, study personnel access the application on a local phone, which in turn accesses the existing clinical trial database hosted on a US web server. The application retrieves a list of participants with the following information: phone number, whether a message should be received at that time, and the appropriate text of the message. The application is capable of storing multiple outgoing messages. With a few clicks, text messages are sent to study participants who can reply directly to the message. Study staff can check the local phone for incoming messages. The SMSMessenger application uses an existing clinical trial database and is able to receive real-time updates. All communications between the application and server are encrypted, and phone numbers are stored in a secure database behind a firewall. No sensitive data are stored on the phone, as outgoing messages are sent through the application and not by messaging features on the phone itself. Messages are sent simultaneously to study participants, which reduces the burden on local study staff. Costs and setup are minimal. The only local requirements are an Android phone and data plan. CONCLUSION: The SMSMessenger technology could be modified to be applied anywhere in the world, in any language, script, or alphabet, and for many different purposes. The novel application of this existing low-cost technology can improve the usefulness of text messaging in advancing the goals of international clinical trials.

RESUMEN

Unhealthy alcohol use, highly prevalent in the Russian Federation (Russia), is associated with HIV risk behaviors among people living with HIV (PLWH). HIV stigma contributes to the HIV risk environment in Russia. To examine HIV stigma among Russian PLWH and to explore its association with unhealthy alcohol use, we conducted a longitudinal analysis of 700 PLWH in St. Petersburg, Russia. We assessed the association between alcohol dependence and HIV stigma measured at baseline and 12 months follow-up. Participants with alcohol dependence (n = 446) reported significantly higher HIV stigma scores over time than those without dependence (n = 254) (adjusted mean difference 0.60, 95% CI 0.03-1.17; p = 0.04). In secondary analyses, we examined recent risky alcohol use and did not detect an association with HIV stigma. Alcohol dependence is associated with high HIV stigma among Russian PLWH but the nature of the association is conjectural. HIV prevention efforts in Russia that address alcohol use disorders hold potential to mitigate HIV-related stigma and its possible adverse effects among PLWH.

RESUMEN

We analyzed baseline data from an observational cohort of HIV-infected ART-naïve patients in St. Petersburg, Russia to explore whether pain was associated with HIV risk behaviors. The primary outcomes were (1) unprotected vaginal or anal sex in the past 90 days and (2) sharing of needles or equipment in the past month. Secondary outcomes included: use of alcohol prior to sex, current injection drug use, number of unprotected sex and sharing episodes, and days injected in the past month. The main independent variable was any past week pain. Multivariable regression models were fit for outcomes. After adjustment, the association with unprotected sex was of borderline significance (AOR = 2.06; 95 % CI 0.98-4.36, p = 0.058); there was no significant association between any past week pain and sharing of needles/equipment (AOR = 1.52; 95 % CI 0.65-3.59, p = 0.33). Participants with pain had higher odds of reporting alcohol use prior to sex (AOR = 2.42; 95 % CI 1.10-5.28, p = 0.03).

RESUMEN

BACKGROUND: Although the association between alcohol and homicide is well documented, there has been no recent study of alcohol involvement in homicide victimization in U.S. states. The objective of this article was to determine the prevalence of alcohol involvement in homicide victimization and to identify socio demographic and other factors associated with alcohol involvement in homicide victimization. METHODS: Data from homicide victims with a reported blood alcohol content (BAC) level were analyzed from 17 states from 2010 to 2012 using the National Violent Death Reporting System. Logistic regression was used to investigate factors associated with the odds of homicide victims having a BAC ≥ 0.08%. RESULTS: Among all homicide victims, 39.9% had a positive BAC including 13.7% with a BAC between 0.01% and 0.79% and 26.2% of victims with a BAC ≥ 0.08%. Males were twice as likely as females to have a BAC ≥ 0.08% (29.1% vs. 15.2%; p < 0.001). Characteristics that were independent predictors of homicide victims having a BAC ≥ 0.08 included male sex, American Indian/Alaska Native race, Hispanic ethnicity, history of intimate partner violence, and nonfirearm homicides. CONCLUSIONS: Alcohol is present in a substantial proportion of homicide victims in the United States, with substantial variation by state, demographic, and circumstantial characteristics. Future studies should explore the relationships between state-level alcohol policies and alcohol involvement among perpetrators and victims of homicide.

RESUMEN

BACKGROUND: World Health Organization (WHO) recommends tuberculosis (TB) screening at HIV diagnosis. We evaluated the inclusion of rapid urine lipoarabinomannan (LAM) testing in TB screening algorithms. METHODS: We enrolled ART-naïve adults who screened HIV-infected in KwaZulu-Natal, assessed TB-related symptoms (cough, fever, night sweats, weight loss), and obtained sputum specimens for mycobacterial culture. Trained nurses performed clinic-based urine LAM testing using a rapid assay. We used diagnostic accuracy, negative predictive value (NPV), and negative likelihood ratio, stratified by CD4 count, to evaluate screening for culture-positive TB. RESULTS: Among 675 HIV-infected adults with median CD4 of 213/mm3 (interquartile range 85-360/mm3), 123 (18%) had culture-confirmed pulmonary TB. The WHO-recommended algorithm of any TB-related symptom had a sensitivity of 77% [95% confidence interval (CI) 69-84%] and NPV of 89% (95% CI 84-92%) for identifying active pulmonary TB. Including the LAM assay improved sensitivity (83%; 95% CI 75-89%) and NPV (91%; 95% CI 86-94%), while decreasing the negative likelihood ratio (0.45 versus 0.57). Among participants with CD4 < 100/mm3, including urine LAM testing improved the negative predictive value of symptom based screening from 83% to 87%. All screening algorithms with urine LAM performed better among participants with CD4 < 100/mm3, compared to those with CD4 ≥ 100/mm3. CONCLUSION: Clinic-based urine LAM screening increased the sensitivity of symptom-based screening by 6% among ART-naïve HIV-infected adults in a TB-endemic setting, thereby providing marginal benefit.

RESUMEN

Poor social support and mental health may be important modifiable risk factors for HIV acquisition, but they have not been evaluated prior to HIV testing in South Africa. We sought to describe self-perceived mental health and social support and to characterize their independent correlates among adults who presented for voluntary HIV testing in Durban. We conducted a large cross-sectional study of adults (≥18 years of age) who presented for HIV counseling and testing between August 2010 and January 2013 in Durban, South Africa. We enrolled adults presenting for HIV testing and used the Medical Outcomes Study's Social Support Scale (0 [poor] to 100 [excellent]) and the Mental Health Inventory (MHI-3) to assess social support and mental health. We conducted independent univariate and multivariable linear regression models to determine the correlates of lower self-reported Social Support Index and lower self-reported MCH scores. Among 4874 adults surveyed prior to HIV testing, 1887 (39%) tested HIV-positive. HIV-infected participants reported less social support (mean score 66 ± 22) and worse mental health (mean score 66 ± 16), compared to HIV-negative participants (74 ± 21; 70 ± 18; p < 0.0001). In a multivariable analysis, significant correlates of less social support included presenting for HIV testing at an urban hospital, not having been tested previously, not working outside the home, and being HIV-infected. In a separate multivariable analysis, significant correlates of poor mental health were similar, but also included HIV testing at an urban hospital and being in an intimate relationship less than six months. In this study, HIV-infected adults reported poorer social support and worse mental health than HIV-negative individuals. These findings suggest that interventions to improve poor social support and mental health should be focused on adults who do not work outside the home and those with no previous HIV testing.

RESUMEN

The impact of depressive symptoms on ART initiation among Russian HIV-infected heavy drinkers enrolled in a secondary HIV prevention trial (HERMITAGE) was examined. We assessed 133 participants eligible for ART initiation (i.e., CD4 count <350 cells/µl) who were not on ART at baseline. Depressive symptom severity and ART use were measured at baseline, 6- and 12-months. Association between depressive symptoms and subsequent ART initiation was evaluated using GEE logistic regression adjusting for gender, past ART use, injection drug use and heavy drinking. Depressive symptom severity was not significantly associated with lower odds of initiating ART. Cognitive depression symptoms were not statistically significant (global p = 0.05); however, those with the highest level of severity had an AOR of 0.25 (95 % CI 0.09-0.71) for delayed ART initiation. Although the effect of depression severity was not significant, findings suggest a potential role of cognitive depression symptoms in decisions to initiate ART in this population.

RESUMEN

History of forced or coerced sex work entry and/or sex work entry prior to age 18 (i.e., sex trafficking) relate to early HIV risk; whether such risk persists is unclear. The current study assessed associations of reported sex trafficking histories and recent sexual risk among adult HIV-infected female sex workers (FSWs; n = 211) in Mumbai, India. Approximately one-half reported entering sex work prior to age 18 (50.2 %) or being forced or coerced into sex work (41.7 %). Past 90-day unprotected transactional sex was more prevalent among FSWs entering as minors than those entering as adults (AOR 2.06); in contrast, being forced or coerced into sex work related to reduction in such risk for HIV transmission (AOR 0.45). Histories of each form of sex trafficking may relate differently to later HIV risk. Intervention with HIV-infected FSWs entering sex work as minors should be prioritized based on potential elevated risk of HIV transmission.

RESUMEN

Overdoses and HIV infection are common among Russians who inject drugs, yet risk factors have not been studied. We analyzed baseline data of 294 participants with 30-day injection drug use from an HIV secondary prevention trial for persons reporting "heavy" alcohol use (National Institute on Alcohol Abuse and Alcoholism [NIAAA] risky drinking definition) and risky sex in the past 6 months. The outcome was any self-reported overdose in the previous 3 months. We examined demographic, HIV-related, criminal justice, mental health, substance use, and injection risk factors. Participants' characteristics included median age 29 years, 117/294 (40%) female, and median CD4 cell count 345/µl. Over three quarters 223/294 (76%) reported a history of overdose and 47/294 (16%) reported overdose in the past 3 months. Past month injection frequency (adjusted odds ratio [AOR] 4.77, 95% confidence interval [CI]: 1.63-14.0 highest vs. lowest quartile; AOR 3.58, 95% CI: 1.20-10.69 second highest vs. lowest quartile) and anti-retroviral therapy (ART) at time of interview (AOR 3.96 95% CI: 1.33-11.83) were associated with 3-month overdose. Nonfatal overdose among HIV-infected Russians who inject drugs is common. Risk factors include injection frequency and anti-retroviral therapy (ART), which warrant further study. Overdose prevention efforts are needed among HIV-infected Russians who inject drugs.

RESUMEN

BACKGROUND: A rapid diagnostic test for active tuberculosis (TB) at the clinical point-of-care could expedite case detection and accelerate TB treatment initiation. We assessed the diagnostic accuracy of a rapid urine lipoarabinomannan (LAM) test for TB screening among HIV-infected adults in a TB-endemic setting. METHODS: We prospectively enrolled newly-diagnosed HIV-infected adults (≥18 years) at 4 outpatient clinics in Durban from Oct 2011-May 2012, excluding those on TB therapy. A physician evaluated all participants and offered CD4 cell count testing. Trained study nurses collected a sputum sample for acid-fast bacilli smear microscopy (AFB) and mycobacterial culture, and performed urine LAM testing using Determine™ TB LAM in the clinic. The presence of a band regardless of intensity on the urine LAM test was considered positive. We defined as the gold standard for active pulmonary TB a positive sputum culture for Mycobacterium tuberculosis. Diagnostic accuracy of urine LAM was assessed, alone and in combination with smear microscopy, and stratified by CD4 cell count. RESULTS: Among 342 newly-diagnosed HIV-infected participants, 190 (56%) were male, mean age was 35.6 years, and median CD4 was 182/mm3. Sixty participants had culture-positive pulmonary TB, resulting in an estimated prevalence of 17.5% (95% CI 13.7-22.0%). Forty-five (13.2%) participants were urine LAM positive. Mean time from urine specimen collection to LAM test result was 40 minutes (95% CI 34-46 minutes). Urine LAM test sensitivity was 28.3% (95% CI 17.5-41.4) overall, and 37.5% (95% CI 21.1-56.3) for those with CD4 count <100/mm3, while specificity was 90.1% (95% CI 86.0-93.3) overall, and 86.9% (95% CI 75.8-94.2) for those with CD4 < 100/mm3. When combined with sputum AFB (either test positive), sensitivity increased to 38.3% (95% CI 26.0-51.8), but specificity decreased to 85.8% (95% CI 81.1-89.7). CONCLUSIONS: In this prospective, clinic-based study with trained nurses, a rapid urine LAM test had low sensitivity for TB screening among newly-diagnosed HIV-infected adults, but improved sensitivity when combined with sputum smear microscopy.

RESUMEN

BACKGROUND: Despite increases in HIV testing, only a fraction of people newly diagnosed with HIV infection enter the care system and initiate antiretroviral therapy (ART) in South Africa. We report on the design and initial enrollment of a randomized trial of a health system navigator intervention to improve linkage to HIV care and TB treatment completion in Durban, South Africa. METHODS/DESIGN: We employed a multi-site randomized controlled trial design. Patients at 4 outpatient sites were enrolled prior to HIV testing. For all HIV-infected participants, routine TB screening with sputum for mycobacterial smear and culture were collected. HIV-infected participants were randomized to receive the health system navigator intervention or usual care. Participants in the navigator arm underwent a baseline interview using a strengths-based case management approach to assist in identifying barriers to entering care and devising solutions to best cope with perceived barriers. Over 4 months, participants in the navigator arm received scheduled phone and text messages. The primary outcome of the study is linkage and retention in care, assessed 9 months after enrollment. For ART-eligible participants without TB, the primary outcome is 3 months on ART as documented in the medical record; participants co-infected with TB are also eligible to meet the primary outcome of completion of 6 months of TB treatment, as documented by the TB clinic. Secondary outcomes include mortality, receipt of CD4 count and TB test results, and repeat CD4 counts for those not ART-eligible at baseline. We hypothesize that a health system navigator can help identify and positively affect modifiable patient factors, including self-efficacy and social support, that in turn can improve linkage to and retention in HIV and TB care. DISCUSSION: We are currently evaluating the clinical impact of a novel health system navigator intervention to promote entry to and retention in HIV and TB care for people newly diagnosed with HIV. The details of this study protocol will inform clinicians, investigators, and policy makers of strategies to best support HIV-infected patients in resource-limited settings.

RESUMEN

BACKGROUND: The Child and Adult Care Food Program is the primary national program that enables child-care settings to provide healthy meals for children. Associations between Child and Adult Care Food Program participation and child health and development and health care utilization are understudied. OBJECTIVE: To assess associations between children's health, development, health care utilization and food security by meal source (child-care-provided vs parent-provided) among children from low-income families with a child care subsidy attending child-care in settings likely eligible to participate in Child and Adult Care Food Programs. DESIGN: The study used repeat cross-sectional surveys (new sample at successive time points) conducted year-round. PARTICIPANTS AND SETTING: Primary caregivers of 3,084 young children accessing emergency departments or primary care in Baltimore, MD; Boston, MA; Little Rock, AR; Minneapolis, MN; and Philadelphia, PA, were interviewed between 2010 and 2020. The sample was limited to children aged 13 to 48 months, receiving a child care subsidy and attending child-care centers or family child-care homes ≥20 hours per week. MAIN OUTCOME MEASURES: Outcomes included household and child food security; child health, growth, and developmental risk; and admission to the hospital on the day of the emergency department visit. STATISTICAL ANALYSES: Meal source and participant characteristics were analyzed using χ2 tests; associations of outcomes with parent-provided meals were analyzed with adjusted logistic regression. RESULTS: The majority of children had child-care-provided meals (87.2% child-care-provided vs 12.8% parent-provided). Compared with children with parent-provided meals, children with child-care-provided meals had lower adjusted odds of living in a food-insecure household (adjusted odds ratio 0.70, 95% CI 0.55 to 0.88), being in fair or poor health (adjusted odds ratio 0.61, 95% CI 0.46 to 0.81), or hospital admission from the emergency department (adjusted odds ratio 0.59, 95% CI 0.41 to 0.83), with no differences in growth or developmental risk. CONCLUSIONS: Compared with meals provided from home, child-care-provided meals likely supported by the Child and Adult Care Food Program are related to food security, early childhood health, and reduced hospital admissions from an emergency department among low-income families with young children.

RESUMEN

BACKGROUND: Families with versus without children are at greater eviction risk. Eviction is a perinatal, pediatric, and adult health concern. Most studies evaluate only formal evictions. METHODS: Using cross-sectional surveys of 26 441 caregiver or young child (<48 months) dyads from 2011 to 2019 in emergency departments (EDs) and primary care clinics, we investigated relationships of 5 year history of formal (court-involved) and informal (not court-involved) evictions with caregiver and child health, history of hospitalizations, hospital admission from the ED on the day of the interview, and housing-related and other material hardships. RESULTS: 3.9% of 26 441 caregivers reported 5 year eviction history (eviction), of which 57.0% were formal evictions. After controlling for covariates, we found associations were minimally different between formal versus informal evictions and were, therefore, combined. Compared to no evictions, evictions were associated with 1.43 (95% CI: 1.17-1.73), 1.55 (95% confidence interval [CI]: 1.32-1.82), and 1.24 (95% CI: 1.01-1.53) times greater odds of child fair or poor health, developmental risk, and hospital admission from the ED, respectively, as well as adverse caregiver and hardship outcomes. Adjusting separately for household income and for housing-related hardships in sensitivity analyses did not significantly alter results, although odds ratios were attenuated. Hospital admission from the ED was no longer significant. CONCLUSIONS: Demonstrated associations between eviction and health and hardships support broad initiatives, such as housing-specific policies, income-focused benefits, and social determinants of health screening and community connections in health care settings. Such multifaceted efforts may decrease formal and informal eviction incidence and mitigate potential harmful associations for very young children and their families.

RESUMEN

BACKGROUND: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) improves health outcomes for participating mothers and children. Recent immigration policy changes increased chilling effects on WIC access and utilization. Associations between WIC participation and neonatal outcomes among infants born to immigrant parents-23% of all births in the United States-are understudied. OBJECTIVE: Our aim was to examine relationships between prenatal participation in WIC and birth weight among infants of income-eligible immigrant mothers. DESIGN: The study design was repeat cross-sectional in-person surveys. PARTICIPANTS/SETTING: Participants were 9,083 immigrant mothers of publicly insured or uninsured US-born children younger than 48 months accessing emergency departments or primary care in Baltimore, MD; Boston, MA; Little Rock, AR; Minneapolis, MN; and Philadelphia, PA interviewed from 2007 through 2017. MAIN OUTCOME MEASURES: Outcomes were mean birth weight (in grams) and low birth weight (<2,500 g). STATISTICAL ANALYSES: Multivariable linear regression assessed associations between prenatal WIC participation and mean birth weight; multivariable logistic regression examined association between prenatal WIC participation and low birth weight. RESULTS: Most of the immigrant mothers (84.6%) reported prenatal WIC participation. Maternal ethnicities were as follows: 67.4% were Latina, 27.0% were Black non-Latina, 2.2% were White non-Latina, and 3.5% were other/multiple races non-Latina. Infants of prenatal WIC-participant immigrant mothers had higher adjusted mean birth weight (3,231.1 g vs 3,149.8 g; P < .001) and lower adjusted odds of low birth weight (adjusted odds ratio 0.79, 95% CI 0.65 to 0.97; P = .02) compared with infants of nonparticipants. Associations were similar among groups when stratified by mother's length of stay in United States. CONCLUSIONS: Prenatal WIC participation for income-eligible immigrant mothers is associated with healthier birth weights among infants born in the United States, including for those who arrived most recently.

RESUMEN

AIM: This study aimed to analyze the association between any past-month cannabis use and advanced liver fibrosis. BACKGROUND: Cannabinoid receptors play a role in acute and chronic liver injury, but human studies addressing the impact of cannabis use on liver fibrosis have shown mixed results. OBJECTIVE: The objective of this study was to explore and estimate the association between pastmonth cannabis use and advanced liver fibrosis (ALF) in a cohort of Russian HIV-positive individuals with heavy alcohol use and a high prevalence of hepatitis C virus (HCV) coinfection. METHODS: Baseline data were analyzed from participants of the ZINC study, a trial that enrolled HIV-positive Russian patients without prior antiretroviral therapy. Cannabis use during the prior month was assessed at study entry. ALF was defined as FIB-4>3.25 and APRI>1.5. Transient elastography was used to detect advanced liver fibrosis among participants with FIB-4 values in the intermediate range (between 1.45 and 3.25). RESULTS: Participants (n=248) were mostly male (72.6%), young (median age of 33.9 years), infected with HCV (87.9%), and did not have advanced immunosuppression (median CD4 count 465). Cannabis use was uncommon (12.4%), and the prevalence of advanced liver disease was 21.7%. The prevalence of ALF was similar among those who used cannabis compared to those who did not (25.8% vs. 21.7%). We were unable to detect an association between cannabis use and ALF (adjusted odds ratio: 1.28, 95% confidence interval: 0.53-3.12, p=0.59) in logistic regression models adjusting for age, sex, heavy drinking, BMI, and CD4 cell count. CONCLUSION: In this exploratory study among HIV-positive heavy drinking Russians, we did not detect an association between recent cannabis use and ALF. Larger scale studies, including more participants with cannabis use, are needed to examine this relationship further.

RESUMEN

People living with HIV (PLWHIV) have been involved in the continuum of HIV care since the early days of the epidemic providing education and prevention services. There is a growing interest in utilizing HIV positive peers to support access to care and treatment, but little is known about the range of roles these peers perform and what they need to know to do this work. This study of 186 HIV-positive peers currently providing community health services in eight states found that peers perform a wide range of roles, including assistance with care and treatment, emotional support, and service referrals. Over 80% discussed medications with clients. On average, experienced peers provided correct responses to 73% of questions about HIV and AIDS, and 65% of questions about the appropriate role of a peer. Peers living with HIV for more than 5 years, in paid employment with more than a high school education had higher HIV knowledge scores than volunteers. Higher education, length of time living with HIV, age and speaking English as the primary language were associated with higher peer knowledge scores. This study suggests that we cannot assume that peers already working in the field are fully knowledgeable about HIV care and treatment or peer roles. It is important to address gaps in knowledge through continuing education and to create common standards for the training and skills that peers who work in community health settings need to have.

RESUMEN

OBJECTIVE: Among US-born children of Latina US (USB) and Latina foreign-born mothers (FBM), to determine whether 1) household and child characteristics differ; 2) child health outcomes differ; 3) these differences diminish for children of FBM with longer duration of residence in the United States; and 4) these differences can be explained by food insecurity (FI) or by Supplemental Nutrition Assistance Program (SNAP) participation. METHODS: Cross-sectional survey of 2145 Latina mothers of publicly insured US-born children 0 to 48 months old in a Boston emergency department (ED) 2004 to 2013. Predictors were FBM versus USBM and duration of residence in the United States. Outcomes were mothers' report of child health, history of hospitalization, developmental risk, and hospital admission on the day of ED visit. Multivariable logistic regression adjusted for potential confounders and effect modification. RESULTS: FBM versus USBM households had more household (31% vs 26%) and child (19% vs 11%) FI and lower SNAP participation (44% vs 67%). Children of FBM versus USBM were more likely to be reported in fair/poor versus good/excellent health (adjusted odds ratios 1.9, 95% confidence interval [1.4, 2.6]), with highest odds for children of FBM with shortest duration of residence, and to be admitted to the hospital on the day of the ED visit (adjusted odds ratios 1.7, 95% confidence interval [1.3, 2.2]). SNAP and FI did not fully explain these outcomes. CONCLUSION: When providing care and creating public policies, clinicians and policymakers should consider higher rates of food insecurity, lower SNAP participation, and risk for poor health outcomes in Latinx children of FBM.

RESUMEN

Importance: Zinc supplementation can reduce alcohol-related microbial translocation and inflammation. Objective: To assess whether zinc supplementation reduces markers of mortality and risk of cardiovascular disease, reduces levels of inflammation and microbial translocation, and slows HIV disease progression in people with heavy alcohol use who are living with HIV/AIDS. Design, Setting, and Participants: This study is a double-blinded placebo-controlled randomized clinical trial of zinc supplementation among participants recruited from 2013 to 2015. Participants were recruited from HIV and addiction clinical and nonclinical care sites in St Petersburg, Russia. Participants were adults (aged 18-70 years) with documented HIV infection who were antiretroviral therapy-naive at baseline and had past 30-day heavy alcohol consumption. Data analysis was performed from February 2017 to February 2020. Intervention: Pharmacy-grade zinc gluconate supplementation (15 mg for men and 12 mg for women, taken daily by mouth for 18 months) was compared with a placebo. Main Outcomes and Measures: The primary outcome was mortality risk measured as a change in Veterans Aging Cohort Study (VACS) Index score between baseline and 18 months. The VACS Index scores range from 0 to 164, with higher scores indicating higher mortality risk. Secondary outcomes were change in CD4 cell count between baseline and 18 months, the assessment of cardiovascular disease risk (Reynolds Risk Score, which ranges from 0% to 100%, with higher scores indicating higher risk), and changes in inflammatory or microbial translocation biomarkers at 18 months. Adjusted linear regression analyses were performed. Results: A total of 254 participants (184 men [72%]; mean [SD] age, 34 [6] years) were enrolled in the trial; 126 were randomized to receive zinc, and 128 were randomized to receive placebo. Participants had high CD4 cell counts (mean [SD], 521 [292] cells/mm3), and 188 (74%) reported heavy drinking in the past week. In the main analyses, zinc supplementation did not affect changes in the VACS Index score at 18 months (change for zinc, mean [SD], 0.49 [14.6]; median [interquartile range], 0.0 [-7.0 to 6.0]; change for placebo, mean [SD], 5.5 [17.2]; median [interquartile range], 6.0 [-6.0 to 14.0]; adjusted mean difference [AMD], -4.68; 95% CI, -9.62 to 0.25; P = .06) or any secondary outcomes, including change in CD4 cell count (AMD, 41.8 cells/mm3; 95% CI, -20.3 to 103.8 cells/mm3; P = .19), Reynolds Risk Score (AMD, -0.014; 95% CI, -0.167 to 0.139; P = .85), interleukin-6 level (AMD, -0.13 pg/mL; 95% CI, -0.38 to 0.11 pg/mL; P = .30), dimerized plasmin fragment D level (AMD, -0.21 µg/mL fibrinogen equivalent units; 95% CI, -0.48 to 0.07 µg/mL fibrinogen equivalent units; P = .14), soluble CD14 level (AMD, -38.01 ng/mL; 95% CI, -166.90 to 90.88 ng/mL; P = .56), intestinal fatty acid binding protein level (AMD, 0.08 pg/mL; 95% CI, -0.07 to 0.22 pg/mL; P = .32), and lipopolysaccharide binding protein level (AMD, -0.09 ng/mL; 95% CI, -0.23 to 0.06 ng/mL; P = .24). In the per-protocol analyses, zinc supplementation statistically significantly affected changes in the VACS Index score at 18 months (AMD, -7.49; 95% CI, -13.74 to -1.23; P = .02); however, the adherence rate to zinc supplementation was 51%. Conclusions and Relevance: Zinc supplementation did not reduce mortality risk, CD4 cell counts, cardiovascular disease risk, and levels of inflammation or microbial translocation in people with heavy alcohol use who are living with HIV/AIDS. Zinc supplementation did not change the VACS Index score but may have been limited by low adherence. Trial Registration: ClinicalTrials.gov Identifier: NCT01934803.
